A new product by StroNGER, currently under development in collaboration with ESA: an advanced sensor for the optimum energy management in building HVAC (Heating, Ventilation and Air Condition) systems. Essentially, PiezoTSensor consists in an Energy Harvesting (EH) device that uses a piezoelectric bender and an appropriate customizable aerodynamic fin that takes advantage of specific air flow effects (principally Vortex Shedding) for producing energy. The sensor is completed with a temperature probe.
